What is the difference between a hypothesis and thesis?

Both the hypothesis statement and the thesis statement answer a research question.
A hypothesis is a statement that can be proved or disproved. It is typically used in quantitative research and predicts the relationship between variables.
A thesis statement is a short, direct sentence that summarizes the main point or claim of an essay or research paper. It is seen in quantitative, qualitative, and mixed methods research. A thesis statement is developed, supported, and explained in the body of the essay or research report by means of examples and evidence.
As an additional note, a good hypothesis will be written as a statement or question that specifies:
The dependent variable(s): who or what you expect to be affected.
The independent variable(s): who or what you predict will affect the dependent variable
What you predict the effect will be.
